LEATHER-WORKING- TOOL.

Application filed Decemser 20, 1927. Serial No. 241,360.

T he present invention relates to improve- ,1 ments in tools and hasreference more particularly to an implement that is adapted to be usedin cutting strips of leather of various widths in a simple and efiicientmanner. V j 7 Another important object of the invention is to provide atool of the above mentioned character wherein means is provided forcreasing the strip of leather, additional means being associated withthe tool whereby holes may be punched in the-strip.

A further object of the invention is to provide a tool of the abovementioned character wherein the blade carrying gage bar may be adjustedto facilitate the cutting of strips of leather of any-desired width,means being provided ior securing the slidable gage bar in its adjustedposition.

A still furtherobject is to provide a tool of the above mentionedcharacter which is simple in construction, inexpensive, strong anddurable and further well adapted to the purpose for which it isdesigned.

Other objects and advantages'of the invention will become apparent fromthe following description when taken in connection with the accompanyingdrawing.

In the accompanying drawing forming a part of this specification,wherein'like reference characters indicate like parts:

Figure 1 isa top plan view of the leather working tool embodying myinvention.

Figure 2 is an edge elevation, and Figure 3 is a side elevationot thetool. In the drawing wherein for the purpose of illustration is shownthe preferred embodiment of my invention, the numeral 1 designatesgenerally my improved leather working tool, the same comprising asubstantially rectangular shaped metallic body 2 that is solid and thathas formed at its inner end, a

downwardly curved handle The solid body 2 is formed with a transverseslot that extends through the opposite sides thereof, and the purpose ofthis slot will be presently described. I

A substantially U-shaped yoke member denoted by the numeral 4 and formedfrom a single strip of flat metal has its crown portion spaced from theouter end of the solid body 2, the arms 5 of this yokemember beingdisposed against the respective sides of the body as clearly illustratedin Figure 1. The arms 5 are formed with the elongated registering slotsthat communicate with the slot t torm ed in the body 2. A laterallyextending linger 6 is formed onthe upper edge of the innermost arm atthe freeend thereof,

and the purpose of this finger or ear will be hereinafter more fullyexplained.

A gauge bar 7 is slidablethrough the slot formed in the solid bar 2 andalso through the registering slotsformed in the intermediate portions oithe arms 5 of the yoke, member 4, and the upper face of this gauge baris provided. with a conventional scale 8 as shown very clearly inFigure. 1.

A vertically disposed cutting blade 9- is formed at its lower end with alaterally 'ex-,

tending attaching flange'lOcthat vis adapted to be secured to the innerend of the bar 7 in any appropriate manner such as is shown at 11 withreference more particularly to Figure 2 and the cutting edge ofthebladefaces the handle portion 3 and is disposed at extreme inner endof the bar.

For the purpose of locking the slidable bar, it:

7 in a fixed position so that the cutting blade 9 may be held in properspaced relation with respect to the inner side of the body 2, I providea block 12 that is disposed-between the outer end of the body 2 and thecrown pore I tion of the yoke A and a thumb screw 13 ex: tends through asuitable opening. in the crown portion of the yoke and is threadedthrough an. opening formed in the center of the block 12, the inner endof the thumb screw.

engaging the outer end of the body 2 and manifestly by turning the thumbscrew in one direction, said block 12 willcooperate with the yoke toeffect a sliding movement thereof in an outward direction so that theslotted arms 5 of theyoke will engage the rear edge of the guide bar andforce the forward edge of the bar into engagement with the forward edgeof the slot formed in the 7 body, and in this manner, the slidable barwill be locked in its adjusted position.

The outer end of the gage bar 7 is formed with a threaded opening toreceive the externally threaded portion of a leather punch with a toolengaging head715.

A leather creaser 16 is carried by the lower end of the handle portion 3for the purpose of creasing the strip of leather'in the'man- 14, saidpunch being formed at its upper end In use, the thumb screw 13isloosened to r permit the free slidingmovementof the gage bar 7 withrespect to the solid body 2 whereby the blade 9 may be moved laterallywith respect to the body in order to permit the proper width of thestrip that is to be cut from the large piece of leather to be accuratelymeasured and in this manner the scale 8 provides a meansto readilyascertain the distance between the cutting edge ofthe blade 9 andtheinnermost arm 5 of the yoke d. After .the blade has been properlyadjusted or spaced with respect to the body 2, the set screw 13' istightened whereby to lock the gage bar inits adjusted position againstslidll'l'gIIlOVBIIlGIlt; The handle 3 is then grasped w1th=one'of thefingers oi? the-operator being in=engagementwith the finger grip 1'? andthe toolis-then' drawn toward theperson using thesame, one edge of theleather being disposed against the inner arm 5 of the yoke 4 and thelaterally extending finger or ear 6 will=be disposed=above the upperface of the j leather to insure the proper positioning of the same. Thecutting edge of the blade will therrcut through the leather in thismannera strip' of any desired width may be cut from alarge piece ofleather. The'creaser 16 may then be usedfor creasing the strip along itsedge portion and the punch let is then utilized for the purpose offormingone or more holes'in' the strip. 7

It will thusbe seen from the foregoing description, that I have provideda leather working toolwhich will at all times be positive and'eificientin its operation, and due'to its'simplicity the blade carrying bar canbe readily andeasil yadjusted to cut strips of leather of variouswidths.

Wliile'I have shown the preferredembodimen-t ofmy invention, it is tobeunderstood that various changes in the size, shape and arrangement ofparts may be resorted to V 7 without departing from the spirit of thein-' ventionand"the scope ofthe appended claims.

iHa'ving' thus described the invention, what 1. Ina toolfot the classdescribed, a solid body formed with a'transverse through slot, a

rearwardly extending handle at one end'of through which the bar isslidable, a block disposed between the outer end of the body and thecrown port-ion or the yoke, a screw extending through the crown portionof the yoke and the block and adapted to engage the outer end of thebody for the forcing of the.

yoke outwardly tolockthe bar against slidarm of the yoke'a-t the freeend thereof-to prevent upward movement of the work while the tool is inuse. l

2. In a leather cutting tool of the class described, a solid body, adownwardly curved handle formed on the rear end of the body, saidbody'being provided with a transverse through slot, a substantiallyU-shaped yoke, the crown portion'thereof being spaced from the outer end of the body, the arms of the yoke.

being disposed against the respective sides of the body and formed withslots that register with the slot in the body, a fiat gage bar slidablethrough the communicating slots, a vertically disposed cutting bladecarried by one end of the'gage bar, a block arranged within theyokebetween the outer end of the body and the crown portionof the yoke,a screw extending through the crown portion of the yoke and the blockand adapted'to engage the outer end of the body for moving the yokeoutwardly to lock the bar against sliding movement in any adjustedposition,

and a laterally eXtending'ear formed on the upper edge of the innermostarm of the yoke at the free end'thereot to prevent upward movementof theof the same.

In testimony whereof I affix my signature.
